摘　　要：通过线性扫描伏安(LSV)曲线、循环伏安(CV)曲线、电化学阻抗谱(EIS)和塔菲尔(Tafel)曲线对泡沫镍电极、泡沫铜电极和泡沫铁镍电极的性能进行了研究;并分别以泡沫镍电极、泡沫铜电极和泡沫铁镍电极作为尿液微生物燃料电池(UMFC)阳极,通过启动曲线的测试,对3种泡沫金属电极的性能进行了比较。结果表明,泡沫铜电极的LSV特性、CV特性、EIS特性和Tafel特性均优于泡沫镍电极和泡沫铁镍电极,以其为阳极的UMFC产电稳定电压能够达到356mV;泡沫镍电极的CV特性和LSV特性与泡沫铁镍电极相似,泡沫镍电极的EIS特性优于泡沫铁镍电极;泡沫铁镍电极的性能优于泡沫镍电极,以泡沫铁镍电极为阳极的UMFC产电稳定电压能够达到110mV。Through testing of linear sweep voltammetry（LSV）,circulation voltammetry（CV）,electrochemi- cal impedance spectroscopy（EIS）,and Tafel,we studied the electrochemical performances of three foam metal anodes, including nickel foam anode（Ni-anode）, copper foam anode（Cu-anode）, and iron-nickel foam anode（FeNi -anode）. Using Ni-anode, Cu-anode, and FeNi-anode as urine-powered microbial fuel cell（UMFC） anode, respec- tively, we studied their performances by testing start-up curves. The results indicated that, the characteristics of LSV,CV,EIS,and Tafel of Cu-anode were superior to those of Ni-anode and FeNi-anode,and the maximum voltage output of Cu-anode UMFC was 356 mV. The characteristics of CV and LSV of Ni-anode were similar to those of FeNi-anode,and the EIS characteristics of Ni-anode was superior to that of FeNi-anode. The electrochemical performance of FeNi-anode was superior to that of Ni-anode, and the maximum voltage output of FeNi -anode UMFC was 110 mV.
